Question 714842: Hello, thank you for helping me!
Show work please: Use rational zeros theorem to find all the real zeros of the polynomial function. use the zeros to factor f over the real numbers.
f(x)=2x^3 -x^2 +2x -1
Thanks again!

You can put this solution on YOUR website!
f(x)=2x^3-x^2+2x-1
fx=2x^3-x^2+2x-1
fx-2^3+x^2-2x+1=0
±1,±1/2
